Screen Problem with Stan Helsing

[AutomaticDriver]

For the couple of people including me that watched Stan Helsing. Did anybody noticed a couple of times where there was a problem with the picture? One time the screen at the bottom looked liked a old tv when you fast forward a VHS tape( you know those weird lines). One other time it it was weird I cant explain it. But both times it lasted 1 second. Was this a bad disc or what? I am not complaining as it doesnt effect the movie or doesnt make the movie not watchable. Just wondering if others have that kind of problem.
